CORRUGATED METAL END FOR RAILWAY CARS.

Application filed October 1, 1920. Serial No. 414,056.

To allwhom it may concern:

Be it known that I, VINTON E. SISSON, a citizen of the United States, residing at Chicago, in the coimty of Cook and State of Illinois, have invented new and useful Improvements in Corrugated Metal Ends for Railway Cars, of which the following is a specification.

This invention relates to improvements in end structures for railway cars and more particularly to sheet metal ends for freight cars.

The end of a freight car is subject to very severe shocks and stresses on account of the tendency of the cargo to shift when the train starts and stops and in switching and also to the tendency of the superstructure of the car to weave while the train is in motion. To strengthen this type of car, ends have been constructed of one or more sheets or panels of metal, usually steel, which sheets or panels are formed with corrugations for rigidi-fying the structure to more readily meet impacts from without, cargo thrusts from within, and the racking strains from weaving.

It is the object of this invention to provide an end of the' sheet metal type which is adaptable to either wooden car frames or all metal freight cars and that may be employed for strengthening gondola cans, box cars, or other similar cars; It is a further object of this invention to provide the sheets or panels of the end with corrugations of particular contour that from their form and length are peculiarly adapted to meet the stresses and strains already described. While the corrugations are preferably formed parallel, their relation to each other or their direction is immaterial.

Wills the preferred forms of this invention are illustrated upon the accompanying sheets of drawings, yet it is to be understood that minor detail changes may be made without departing from the scope thereof.

\ Figure 4 is a view in section taken on the line H of Figure 2.

Figure 5 is a view in sectiontaken on the line 5-5 of Figure 2.

Figure 6 is a View in section taken on the line 6'6 of Figure 2.

Figure 7 is a fragmentary view of the corner of a panel.

Figure 8 is a sectional view taken on the a line 8-8 of Figure 7 with theparts beyond the line shown in persp'ectivei' The embodiment of this invention is illustrated in the drawings as applied to a box car and shows the end comprising'two or more sheets or panels 1, preferably of pressed steel, which are attached to the corner posts, end plate and end sill in the usual Figure 2 illustrates a means for attaching the panels to the wooden corner posts 2 by flanging the ends of the panels and securing the flanges to the posts. plurality of strengthening corrugations are formed in each panel which merge at their ends into the plane of the panel so that the panel has a flat marginal portion about its e ges.

In the form illustrated in the first eight figures of the drawings the corrugations are pressed from opposite sides'of the sheet or panel with each corrugation having a constant change in depth from the center until it merges into the plane of the panel. The contour of the corrugations at the center is shown in the enlarged sectional view of Figure'3 and the manner in which the corrugations vary and merge into'the plane of the panel is shown in Figures 4, 5 and 6. At the center, the main walls 3 are fiat, equally spaced and substantially perpendicular to the plane of the panel. The main walls are connected at this point by flat portions 4:, the vertical elements of whici are substantially parallel to the'plane of the panel, the portions as a whole sloping irom the center to the ends of the corrugations, where they merge into the margins of the sheet. The flat portions 4: are substantially equal in width to the width of the surface of the main walls. As the corrugations taper from the center toward their ends, the angular relations of the main walls make a constant change, obliquing away from their connecting portions while said portions decrease constantly in width with their longitudinal center lines remaining parallel and said portions on opposite side of the center remaining in the same respective planes until both main walls and connecting portions merge into the plane of the panel.

A wooden lining 7 is provided on th inner side of .the end with a. plurality of filler blocks 8 received Within and attached to a number of corrugations to which the lining is secured. These blocks are tapered and beveled according to the form of corrugation in order that the wooden lining may be secured in a position parallel to the panel.

The corrugations form in effect beams haying compression and tension members with the greatest strength at the center, where it should be, to resist centrally concentrated or equally distributed loads, or impacts in this particular construction. The amount of metal located at a distance from the neutral axis of the panel is constantly reduced from the center to the ends of the corrugations. The maximum stretching or drawing in of the plate in pressing is at the center and is constantly and proportionately reduced from the center to the ends of the corrugations. The compression and tension members are positioned away from the neutral axis of the panel and are connected by the main walls. The compression and tension members, the oppositely disposed flat connecting portions, vary in width from the center to the ends and the angular relation of the webs to the plane of the panel varies from the perpendicular at the center in ac cordance with the width of the compression and'tension members until all merge into the panel.
